I made something on blender and pressed something and now I don’t know how to get back to what I was doing please help!
Sometimes there are situations were it is hard to fix a UI state by hand.
In those extreme cases my favourite way is:


Save current blend-file  
Open second blender instance (on OSX via Terminal https://blender.stackexchange.com/a/102862/68710)  
click: File>Open  
Open your first blend-file but uncheck "Load UI" (on the left panel) before doing so  




now you got your first file but with startup-file-ui
